I remember at primary school bring mortified by an accusation of plagiarism. I think it would have been in Primary Four or Five or Six. We were asked to come up with a slogan for British Rail. Obvious; Let the Train Take the Strain. Apparently, a little too obvious. British Rail had already used it. The teacher accused me in front of the whole class of plagiarism. The thing is, I wouldn't be stupid enough to try to deliberately pass off such a well known slogan as my own work. To me it was obvious. Now whether I'd heard the phrase and it had lodged in my subconscious is another question. But to humiliate me in front of my classmates was not Scottish Teaching's finest moment.
